I am one of the apparently many that didnt find Stacks so good. Actually I found it to be a downgrade compared to Tiger. Especially as an application launcher I thought that Stacks isnt as good as in Tiger. I found out that when u click on the programs stack, then typing the first character of an app, the cursor goes there and u can use the cursor keys to move through the apps. Now I can use stacks as an apps launcher and I am happy about it because it looks also great!
